Skin Barrier Buzz: The importance of your skin barrier and how to repair damaged skin barrier

How to fix skin protein barrier

The latest buzz sweeping the skincare world is all about your skin barrier and why it’s so darn important.

But the importance of your skin barrier isn't a new buzz. It has been around forever. And it should be the foundation of any skincare product you use.

Prioritising skin barrier health is secondnature to those of us in the skincare biz, but it's something we don't talk about enough, so it's a good thing that the skin barrier is having its moment in the spotlight again.

The importance of your skin barrier cannot be underrated. It plays such a big role in our life. And if you have a damaged skin barrier, it can really impact your wellbeing.

The book “Skin Barrier Function” by AJ Kanwar sums it up best

Physically, it protects from external threats such as infectious agents, chemicals, systemic toxicity and allergens. Internally, the skin helps to maintain homeostasis and protects from enhanced loss of water from the body.

If your skin barrier is damaged or unhealthy, skin issues will arise. Dermatitis, Psoriasis, eczema to name a few.

What is your skin barrier?

On the surface (pun intended!) it seems pretty simple, but in fact your skin is a complex and dynamic organism that is continually renewing.

It’s made up of 3 layers:

  1. Epidermis - the outer layer of your skin barrier which is also made up of skin cells, pigment producing cells and immune cells. Yes, your skin is part of your immune system - that’s how cool skin is!
  2. Dermis - the middle layer of your skin barrier where all the collagen and elastin live
  3. Subcutis - the lower level of your skin barrier which is made up of fat cells called adipocytes

For today we will focus on the epidermis and its outermost layer (also known as the stratum corneum) as this is where your skin care products do the bulk of their work helping with skin barrier repair.

The stratum corneum also has a really cool bio chemistry. It is like a brick wall keeping the good stuff (like moisture) in and the bad stuff (like bacteria) out. The bricks are your skin cells which are held together by lipids (ceramides, fatty acids and cholesterol). Keeping this structure strong is key to good skin and a healthy skin barrier.

How do you know if you have a damaged skin barrier?

This is easy, as all it takes is a simple looksee. If your skin looks dry, rough, scaly, red, inflamed or dull then your skin's barrier is not feeling 100% and it’s a sign that your skin barrier is damaged.

It’s good to keep in mind that this can change from one day to the next as your skin is constantly on the defensive from wind, pollution, UV, dirt and bacteria. Also, when your skin is low on hydration the protective "brick wall" starts to break down and issues start to creep in.

Without giving your skin barrier some help your skin will get weaker and more prone to sensitivity and skin issues.

Skin barrier repair: How to fix skin protein barrier

There are plenty of ways you can give your skin a helping hand to ensure your skin barrier remains strong. The key is to keep the water and lipid levels in your skin nice and high. Here are our go-to tips:

  • Drink plenty of water
  • Limit alcohol and coffee intake
  • Eat good fats
  • Reduce the heat in the shower. The cooler the water, the better it is for your skin.
  • Use gentle products. Some soaps, exfoliators and cleansing products can deplete your skin by stripping away it’s natural oils.
  • Be mindful of cleansing devices/cloths/brushes as they can all upset the skin barrier balance if they’re too rough.
  • Avoid fragranced products. Fragrance may smell great but they usually do more harm than good. While synthetic fragrances are at the top of the “NO” list, you also might also need to watch essential oils as these can be issues for some people.
  • Moisturise!! Using a good moisturiser that supports your skin's natural lipids and natural moisturising factor is the best preventative of skin issues. Prevention is better than cure.
